If eighteen-year-old Karki doesn't turn out to be the next Edison, I'll chop off my locks This kid invented a solar pane (嵌板) which uses human hair as a conductor and could provide the world with cheap, green electricity, solving the energy crisis.
Karki, a Nepal teenager, who lives in a village in Rural Nepal, used human hair to replace silicon, which is a common but expensive component of solar panels.
By using hair as a replacement, Karki says solar panels can be produced for around 23 pounds. But if they were mass-produced, Karki says they could be sold for less than half that price, which could make them a quarter of the price of those already on the market.
The solar panel works because melanin, the substance giving hair its color, is light sensitive and can act as an electrical conductor. Karki was inspired to follow this route by a Stephen Hawking book, which explained how to create energy from hair.
The device (设备) Karki has shown is able to produce 9V or 18W of energy -- plenty to charge a mobile phone. Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months, where as a pack of batteries would cost 50p and last a few nights," according to Karki.
Karki has now sent out several devices to other districts near his village for testing. "First I wanted to provide electricity for my home, then my village. Now I am thinking for the world," he said.
Karki says the idea is more important than ever because of the urgent need for renewable energies in the face of limited power sources and global warming. Slowly, natural resources are decreasing. One day we will be in a great crisis. This is an easy solution for the crisis we are having today.

C. Special Solar panel Materials                      D. Karki Invented a New Solar Panel
65. Why did Karki want to invent a solar panel with hair?
A. Because hair is not very expensive.
B. Because silicon is hard to find.
C. Because he wanted to provide electricity for his home.
D. Because the energy crisis is very serious in his home town.

A, Karki s invention is of great importance
B. Karki can predict what will happen in the future
C. the energy crisis will disappear in the future
D. Karki's invention will make him wealthy

Isaac Newton: The Last Sorcerer
Michael White
From the author of Stephen Hawking: A Life in Science, comes this colorful description of the life of the world’s first modern scientist. Interesting yet based on fact, Michael White’s learned yet readable new book offers a true picture of Newton completely different from what people commonly know about him. Newton is shown as a gifted scientist with very human weaknesses who stood at the point in history where magic (魔术)ended and science began.

Fermat’s Last Theorem
Simon Singh
In 1963 a schoolboy called Andrew Wiles reading in his school library came across the world’s greatest mathematical problem: Fermat’s Last Theorem (定理). First put forward by the French mathematician Pierre de Fermat in the seventeenth century, the theorem (法则)had baffled and beaten the finest mathematical minds, including a French woman scientist who made a major advance in working out the problem, and who had to dress like a man in order to be able to study at the Ecole
Polytechnique. Through unbelievable determination Andrew Wiles finally worked out the problem in 1995. An unusual story of human effort over three centuries, Fermat’s Last Theorem will delight specialists and general readers alike.

Should we try to contact and make friends with other beings in the universe? Certainly not，says British physicist Stephen Hawking．

“If aliens（creatures from other planets）ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,’’ said the 68-year-old disabled scientist in a new Discovery documentary (纪实性电视节目) on April 25．

The program pictures an imagined universe where other life forms in huge spaceships hunt for resources after using up all those on their home planets．

“Such advanced aliens would perhaps become nomads(游牧民)，looking to conquer and colonize whatever planets they can reach，”warned Hawking．

On the probability of other life forms existing, he says, “To my mathematical brain, the numbers alone make thinking about aliens perfectly reasonable.”

Hawking’s concerns have frightened some people and been met with disagreement from other researchers．Paul Davies, author of the book Renewing Our Search for Alien Intelligence，thinks Hawking’s reasoning is wrong.

He argues that since Earth is about 4.5 billion years old，if intel1igent life is likely , communities of other beings may have been there for a very long time．

“If resources are the factor, then at least one group of aliens would surely have visited Earth as a destination mil1ions of years ago．

Even if other life forms do come to Earth in the near future, Davies believes comparisons with are wide of the mark(离谱的).

68. What is the article mainly about?

A. Other life forms coming to our planet．

B. Scientific evidence of other life forms．

C. Earth as the only place where human beings can survive．

D. Hawking’s belief that other life forms may exist in the universe．

69. Which of the following ideas is opposed to Hawking’s view?

A. Other life forms exist in the universe．

B. 0ther life forms may be more intelligent than human beings．

C. We should try to contact other 1ife forms from other planets．

D. Other life forms may exist in more than one part of the universe．

70. Paul Davies didn’t agree with Stephen Hawking ,believing that ________．

A. the universe is running out of resources

B. humans are the best creatures in the universe.

C. it is a good idea to avoid meeting with other life forms

D. Davies doesn’t think it proper to compare aliens with Columbus

71. Hawking referred to Christopher Columbus as an example to ____．

A. inspire interest in the universe

B. draw attention to other planets in the universe

C. warn people to watch out for other life forms

D. urge further exploration of the universe~

Hawking has left much for Chinese to think about.

British physicist Stephen hawking, possible the world’s most famous scientist after Albert Einstein, gave lectures in Zhejiang and Beijing in August.

An illness left him unable to move any part of his body except for three fingers. But his continuing efforts in the field of science have made many young people take him as their idol（偶像）.

His books, such as A Brief History of Time, become bestsellers in Chinese bookstores. “Hawking helps people enlarge their horizons and become interested in science,” said Pan Yunhe, president of Zhejiang University.

Indeed, experts don’t think it likely that Hawking’ s lectures and profound（深奥的） ideas will be easily understood by the average person. But he has certainly sowed the seeds of science among many young people.

And the “Hawking fever” caused by his visit has made people ask: How can China produce more top scientists like Hawking?

“Nurturing（培养）top scientists will take as much work to change society as to educate the scientists themselves,” said Zhang Fan. Zhang has studied in the UK since 1999 and will be a second – year student at Trinity College in October.

In Britain, Zhang said, teachers inspire students to have a general understanding of the subjects they are interested in. And they encourage students to develop new ideas, which helps them to nurture their creativity.

In China, the Department of Education has encouraged schools to provide quality education to develop students’ potential（潜力）.

“I hope teachers will pay more attention to helping us use our imaginations and solve problems on our own,” said Lu Jie, a Junior Three student in Sanfan Middle School in Beijing.

63. _________ have made young people take Hawking as their idol.

A. Hawking’ s ongoing devotion to science

B. the fact that Hawking is a famous physicist

C. Hawking’ s lectures in Zhejiang and Beijing

D. the fact that Hawking can just move three fingers

64. In paragraph 4, the underlined word “horizons” means “_________”.

A. one’s knowledge of science B. one’s sight of the subjects

C. the area of one’s knowledge D. the line where earth and sky meet

65. From the passage we learn that _______.

A. Hawking’ s books were not popular in China before his visit

B. most schools in China provide quality education to develop students’ potential

C. to nurture top scientists, teachers should solve all the problems for the students

D. ordinary people in China may find Hawking’ s ideas beyond their comprehension

66. The last three paragraphs mainly tell us_______.

A. students in Sanfan middle school are more imaginative

B. teachers should encourage students to be more creative

C. British students do not work as hard as Chinese students

D. top scientists won’t appear even if schools provide quality education
